To THE CINCINNATI CAR ooRPoIATIoN, or WINTON PLACE, oHIo, A doRPoItA- TION OF OHIO y RAILWAY CAIR original application mad :December 9, 1925, serial No. 74,324. Divided'ana this application filed Augiis't" 5, 1926. serial No. 127,451.

This invention relates to improvements in structural frames for use in building railway car bodies, particularly interurban and city railway cars, although the inveiltion is applicable to the construction of motor buses and horse-drawn Vellicles such as omnibuses and passenger transfer collveyances colnmonly known as depot Wagons.

More particularly this invention constitutes an ilnproveinent in or addition to the structural frame set forth and claimed in my application filed November 3, 1925, Serial No. 66,633, and assigned to my present assignee, The Cincinnati Gar Company.

The essential features of the present invention consist of a structural fralne of the character set forth in my other application illiproved by the provision of a series of ventilating openings in one bar or member of such frame, which openings lead from the outside to the inside of the car, .and an open-Work slide or damper placed across such openings in the frame bar and adapted by adjustment to more or less open and shut the Ventilating l openings according as a passenger' may desire.

A further feature of this invention consists of certain bell crank push buttons byv which the passenger may adjust the slide with respect to the openings in the frame, and of springs which act to hold the slide in any adjusted position.

In the accompanying drawings:

Figure 1 is an enlarged detail elevation looking at the inner side of one wall of a car with my Ventilating devices inoulited therein;

Figure 2 is an enlarged detail view of a part of the structural frame and a part of the sash with my Ventilating improvements shown on an enlarged scale;

Figure 3 is a longitudinal sectional view on the line 3-3 of Figure 2, showing the parts partly in section and partly iii plan;

Figure 4 is a longitudinal sectional View of the ventilator slide on an enlarged scale;

Figure 5 is a side elevation of such slide;

Figure 6 is a-longitudinal sectional VieW through the front plate; and

Figure 7 is a side elevation of such plate.

Referring to Figure 1, an interior View looking toward one side of the car, it will be frames are provided with openings 2 in the f Vouter wall of the lower member or bar anda general opening 3 in the inner Wall. The openings 2 are opened and closed by a sliding damper 4 in the nature of a plate vhaving a succession of openings 5 corresponding in size and position with the openings 2 in the structural frame, as clearly seen in Figure 3. This damper slide is fitted to rest on the interior of the lower bar ofthe structural frame as indicated generally in Figure 3. It is held f i in place agaillstthe frame by coil springs 7 clearly shown in Figure 3. These springs are mounted on bell crank push buttons 8 and bear at one end on the shoulder 9 and at thel other end against a Washer 10 which in turn is to be pressed against the cross pin l11 carried by the sliding damper 4. In this way the dalnper is properly held against the Wall of the structural fralne in any position` to which it maybe adjusted by pushing inward on one or the other of the push button surfaces 12 `of the push button levers. For instance, when the Ventilating damper is in the position shown in Figure 3 the springs are exerting a pressure against itin a direction to the right of the pivots of the bell crank levers, While if the damper is adjusted to the other extreme position these springs will be exerting their pressure in a line at the left of tlieir'pivots.

Again, if the damper is adjusted, say half Way acrossthe Ventilating openings 2, the springs will exert their pressure directly against the damper and by the friction thus created between tlle damper and the Wall of the structural frame,lwill hold the damper in such position. l

The numeral 13 refersto a front plate secured as by screws 14 to the inner face of the structural fralne. This `plate has Ventilating openings 15 so that Whatever air is let in through the openings 2 in the structural frame and-through the damper will enter the car.

The sash actuating mechanism comprises a shaft 21 rotatably mounted in the plate 13, the plate 13 servingas a bearing for the shaft.v Mounted-upon the shaft is an eccentric 19, carrying the arms 17 and 17a, these arms terminating in projections 18 and 18a respectively, Which projections engage the rack bar 16, secured to the frame for operating the Win-- dow sash. The shaft and ar'ms are operated` by means of a crank 20 provided with a handle 20a, the crank 20 being sccuredfto the-shaft 21 at the point 22; It will thus be seen that by rotating the shaitz21, either: arm-171 011.17. maybe brought into engagen'ient withthe rack bar to openor close the Window as desirled.-y These features are more fully set forth in my copendingapplication, Serial 74,324, filed Decembery 9,- 1925', of which this present.` application is a division.

'Ilhus itrWill be understood that I have provided a practical means by which limited quantities of the outer air may be admitted into the car for purposes of -ventilation. Again, the Ventilating damper may be opened without movingthe Window sash.

Itwill be'vunderstood that1I desire to comprehend Within my invention such modificaf tions as maybe necessary to adapt it to varying4 conditions andi uses.

Havingithus fully described "my invention, What-I claim as new` and=desire to secure by Letters Patentis::

1. The-combination with a ca-r structural frame havingventilating openings inone of f the damper` is adj usted and whereby. through the actionofthe.y springsthe damper is held in any, adjusted position. j

3; The combination with a carstructural frame having al. hollovv` bar and Ventilating openings in the outer wall; ofa damper mounted within the: bar and slidable across said o enings, and A.bell crank! leversmounted in the: var, connected 'at one end to the damper and hand-operable attheV other end.

4: Thelcombinationfiwith a car` structural frame v havingza hollow. barl and Ventilating openings in the outer Wall, of aA damper mounted within the bar-and slidable across said openings, bell crank leversmounted in the'lbar, `connected lat; one end ,to tlief damper and hand-operable at the other end, and a coil spring mounted on each lever and arranged to exert pressure against the damper to hold it in any adjusted position.

5. The combination with a car structural frame, having ventilating openings through which air may be admitted into the car,.ofv a Jion-pivoteddamper to controlsaid openings, means to adjust the damper in one direction and a second means to adjust said damper in the other direction, said damper, and the means to adjust it, being mounted in said frame. I

6. The combination with a car structural frame, having Ventilating openings to admit air into the interior'o the car, of a nonpivoted damper mountedl in saidjframe to control the vadmission andyiexclusion off the air, pushfbutton means mounted in the-frame to adjust said damper in one direction and a second' push: ybutton means to adjust, the damper-in another direction.v

In testimony whereof, ,I1 aiix my signature.
